The gear boxes are made of stainless steel, except from the insight flanges which are constructed of anodized aluminum. Security class IP65 is regular – IP67 offered as choice – which is acheived using a patented insight sealing and a patented output sealing system.
Standard backlash is just 5 respectively 7 arc-minute (1 resp. 2 phases), reduced backlash is merely 3 / 5 arc-min (choice) and lastly micro backlash is 1 / 31 / 3 arc-min (option).
This means that the actual backlash at a certain load is MUCH Low in an APEX gear box than in virtually any other planetary gear box on the market.
Gearboxes provide torque multiplication, speed decrease, and inertia matching for motor-driven systems. Servo systems, particularly, require gearboxes that can supply not only high torque with low added inertia, but also high precision and stiffness. One kind of gearbox meets each one of these requirements while providing relatively long operating life with zero-maintenance requirements: the planetary gearbox.
A planetary gearbox consists of multiple planetary gears that revolve around a central sun equipment while engaging with an internal gear and rotating by themselves axes. The constant engagement of the planetary gears means the strain is shared by multiple tooth, allowing planetary styles to transmit high torque loads.
This load sharing among teeth also gives planetary gearboxes high torsional stiffness, making them well suited for processes that involve frequent start-stop motions or changes in rotational direction, which are common characteristics of servo applications. Most servo applications also require very exact positioning, and planetary gearboxes were created and manufactured to have low backlash, with as little as 1-2 arcmin in some cases.
Planetary gearboxes can use spur or helical gears. While spur gears can have got higher torque rankings than helical gears, helical designs have smoother operation, less noise, and higher stiffness, producing helical planetary gearboxes the favored gearbox for servo applications.
When a gearbox is added to the drivetrain, the rotational quickness delivered from the motor to the driven component is reduced by the quantity of the gear ratio, that may allow the system to make better use of the servo motor’s speed-torque characteristics. Planetary gearboxes are able to accept very high input speeds and offer speed reduced amount of up to 10:1 for standard styles, with high-speed styles providing equipment ratios (and, therefore, swiftness reduction) of 100:1 or higher.
Planetary gearboxes can be lubricated with either grease or oil, although a planetary gearbox for servo use (sometimes referred to as a “servo rated” or “servo” gearbox) is often lubricated with grease. In either case – grease or essential oil lubrication – planetary gearboxes tend to be lubricated for the life of the gearbox by the product manufacturer, which eliminates maintenance for the end user.
The most important benefit of utilizing a gearbox in a servo system is arguably its effect on the inertia of the load. The load inertia, which is certainly reflected to the motor, is decreased by the sq . of the gear ratio. So even a relatively small gear decrease can have a significant influence on the inertia ratio.
A right angle planetary gearbox with output shaft combines the benefits of a compact correct angle gearbox and those of a typical planetary gearbox.
With its versatile mounting options, our right angle gearboxes offer intelligent drive solutions with a compact machine concept. The result shaft gives right angle planetary gearboxes the advantage of a proven and dependable component for the proper angle tranny of torque and velocity.
